FYI I was able to get this to work on my Dell E6520 running windows 7 64-bit on the i7-2620M with 8GB of RAM. It bumped the windows rating up from a 5.2(GPU limited) to 6.3, and i now am able to run 4 monitors(2 form the iGPU and 2 from the eGPU) The eGPU is a Geforce GT 240

Just a note when cleaning up my DSDT file. I had an error for Name (_HID, "*pnp0c14") and i was able to clean this up by just removing the '*' and my DSDT file worked.

I didn't have to do anything fancy besides override my DSDT file. I'm actually able to plug the eGPU in while the computer is ON and running even. :-) (before the DSDT override, plugging in the eGPU would give me an error 12)

1. Run DSDT Editor.bat

2. File -> Extract DSDT

3. Wait a bit, then click 'Device PCI0' - it should be just after your Processor.

4. Scroll down until you see your DWordMemory stuff, go to the bottom of this list.

5. At the bottom add:

-Sorry but for any newbs like me who didn't have luck just clicking on DSDT Editor.bat and having it work. I had the following error in my command prompt, " 'java' is not recognized as an internal or external command". Try updating DSDT Editor.bat to point directly to your java location instead of just listing 'java' i.e. "C:\Program Files (x86)\Java\jre7\bin\java.exe"

-Also I first tried with \Java\j2re1.4.2\ but I guess this was too old of a java version

--Edit--

...wow... didn't even know there were pages, i guess quietrain had my same issue but it looks like he just used kizwan's method through the youtube link
